The yearly inspection of our new furnace and a/c split system was requested this morning and was set for 1-3 pm. William Cohen texted us at 12:41 to let us know he was on his way, then at 12:45 he called us verbally to let us know he was on his way and about 20 minutes out.
He arrived a few minutes after 1:00.
We initially explained a concern that we've had with the fan/furnace unit. When it was installed a year ago the fan was entremely loud, so the tech lowered thefan speed from 5 to 4 which was still pretty loud, especially considering that both my wife and I have hearing issues and blasting the tv when the furnace for cooling was running.
William explained the issue and equipment concerns if the fan was not put at a proper speed for technical reasons and needed to check it out.
William was very methodical and thorough in his approach to fix our concern. The thermostat was checked to find it needed new batteries, so I gave him two AA batteries. We went through the program and set it for what we needed.
He then looked over the furnace and agreed that the fan on cooling was rather loud. I had recently installed French bifold doors with 1/2 louvers in hopes of baffling the sound to minimal effect, sorry to say! Finding no issues with the furnace and hog hair filter we moved on to the a/c unit. William found the thermostat wire outside not protected from hungry rodents, very observant of him, I appreciate that! He then disconnected the system power and installed a flex conduit line topnotch the wiring. Completing that he looked around the a/c wiring supply and noticed there was no surge protection which he then installed.
Finally ready to check our fan noise issue, he put the fan speed down to 3 and checked every supply air register to make sure there was sufficient air flow which all passed. He then set up many thermometers to test for proper ait temp drop from supply and return. Outside he used his lineset to check refrigerent pressures and line temperatures all to his satisfaction. The ability to run the fan on 3 without degrading the equipment was proven to be effective.
William is very personable, proactive, apparently very well trained, experienced, thorough in his methodical approach, communicates effectively and has a grand sense of humor.
I myself am a retired maintenance electrician, pipe fitter and worked commercially on boilers and HVAC systems, so service work was my livelihood. William is an awesome efficient worker, knows what he is doing and a great asset for Done Rite Services.
Thank you for sending him to do our Servicing. From a happy customer.
Sincerely,
